Researchers from Pennsylvania State University in the US found that in two groups of older individuals - one group with arthritis and one with diabetes - the patients who felt more tension with their spouse also reported worse symptoms on those days.
It is important to learn more about how and why symptoms of chronic disease worsen, researchers said. People with osteoarthritis in their knees who experience greater pain become disabled quicker, and people with diabetes that isn't controlled have a greater risk for developing complications.
While previous research has shown a connection between satisfying marriages and better health, both physically and psychologically, there has been a lack of research into how day-to-day experiences impact those with chronic illness.
"We study chronic illnesses, which usually involve daily symptoms or fluctuations in symptoms. Other studies have looked at the quality of someone's marriage right now," Martire said.
"However, we wanted to drill down and examine how positive or negative interactions with your spouse affect your health from day to day," she said.
Data from two groups of participants were used for the study. One group was comprised of 145 patients with osteoarthritis in the knee and their spouses. The other included 129 patients with type 2 diabetes and their spouses.
Participants in both groups kept daily diaries about their mood, how severe their symptoms were, and whether their interactions with their spouse were positive or negative.
The participants in the arthritis and diabetes groups kept their diaries for 22 and 24 days, respectively.
The researchers found that within both groups of participants, patients were in a worse mood on days when they felt more tension than usual with their spouse, which in turn led to greater pain or severity of symptoms.
They also found that within the group with arthritis, the severity of the patient's pain also had an effect on tensions with their spouse the following day.
When they had greater pain, they were in a worse mood and had greater tension with their partner the next day.
"This almost starts to suggest a cycle where your marital interactions are more tense, you feel like your symptoms are more severe, and the next day you have more marital tension again," Martire said.
"We didn't find this effect in the participants with diabetes, which may just be due to differences in the two diseases," she said.
